红外成像制导导弹分布式协同制导律研究

Study on distributed cooperative guidance law for infrared imaging guided missiles

针对红外成像制导导弹协同攻击问题,基于网络同步原理,考虑导引头视场角、攻击时间协同及攻击角度协同约束条件,提出了一种面向协同探测的分布式协同制导律。建立了包含弹目距离、视线角等在内的弹目相对运动方程,并通过坐标转换将攻击时间及攻击角度协同问题转化为弹目距离及弹目视线角的一致性收敛问题。在一致性问题求解过程中,应用分布式一致性策略计算满足导引头视场角约束的纯比例导引的修正量及切向加速度,从而实现了红外成像制导导弹满足导引头视场角约束的攻击时间协同和攻击角度协同,并给出了制导律成立的充分条件与参数的规范化设计方法。设计的分布式制导律具有满足视场角约束、无中心节点、适应非定常导弹速度、通讯代价小的优点,可以有效适用于红外成像制导导弹进行分布式协同制导。

Aiming at the problem of infrared guided imaging missiles cooperative attack,a novel collaborative detection oriented distributed cooperative guidance law considering the restrict of FOV,consensus of impact time and impact angle was proposed based on the network synchronization principle.Firstly,motion equations including relative distance and FOV were established.With the help of coordinate transformation,the consensus problem of impact time and impact angle was converted into the consensus problem of relative distance and FOV.Secondly,the modified component of pure proportional guidance and tangential acceleration based on the distributed synchronization strategy were derived considering restrict of FOV.Finally,sufficient condition to achieve simultaneous attack was proposed,and the parameter design method was given.The proposed guidance law does not rely on the central node and adapts the non-constant velocity.Besides,it has the advantage of considering restrict of FOV and low communication cost.The proposed guidance law is suited for distributed cooperative guidance for infrared imaging guided missiles.
